See Article History Latent heat, energy absorbed or released by a substance during a change in its physical state phase that occurs without changing its temperature.

latent heat of fusion water

The latent heat associated with melting a solid or freezing a liquid is watrr the heat of fusion latent heat of fusion water that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization. The latent heat is normally expressed as the amount of heat in units of joules or calories per mole or unit mass of the substance undergoing a change of state. During melting, the ice absorbs latent heat, which is used to change the state of the water from ice to liquid water. While the ice is absorbing latent heat, its temperature is not changing.

Expert Answer

Because the heat of vaporization is so large, steam carries a great deal of thermal energy that is released when it condenses, making water an excellent working fluid for heat engines. Latent heat arises from the work required to overcome the forces that hold together atoms or molecules in a material. The regular structure of a crystalline solid is maintained by forces of attraction among its individual atoms, which oscillate slightly about their average positions in the crystal lattice.

As the temperature increases, these motions become increasingly violent until, at the melting pointthe attractive forces are no longer sufficient to maintain the stability of the crystal lattice. However, additional heat the latent heat of fusion must be added at constant temperature in order to accomplish the transition to the even more-disordered liquid state, in which the individual particles are no longer held in fixed lattice positions but are free to move about through the liquid.

Latent Heat of Fusion Example Problems with Answers:

A liquid differs from a gas in that the forces of attraction between the particles are still sufficient to maintain a long-range order that endows the liquid with a degree of cohesion. As the temperature further increases, a second transition point the boiling point is reached where the long-range order becomes unstable relative to the largely independent motions latent heat of fusion water the particles in the much larger volume occupied by a vapour or gas.

Once again, additional heat the latent heat of vaporization must be added to break the long-range order of the liquid and accomplish the transition to the largely disordered gaseous state. Latent heat is associated with processes other than changes among the solid, liquid, and vapour phases of a single substance. Jeat solids exist in different crystalline modifications, and the transitions between these generally involve absorption or evolution of latent heat.

The process of dissolving one substance in another often involves heat; if the solution process is a strictly physical change, the heat is a latent heat. Sometimes, however, the process is accompanied by a chemical change, and part of the heat is that associated with the chemical reaction. See also melting.
